Hi
In this post is i have explained how to upload file from android to restful wcf.
And on the .net (wcf end) define a OperationContact as:
[OperationContract]//(IsOneWay = true)
[WebInvoke(RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.WrappedRequest,
UriTemplate = "/ProcessCheckInRequestMobile? param0 ={ param0}& param1 ={ param1}& param2 ={ param2}&filename={filename}&fileExtension={fileExtension}& param3={ param3}")]
string ProcessCheckInRequestMobile(string param0, string param1 , string param2 , string filename,string fileExtension, long param3 , Stream data);
